[求助] 求助如何解决Error in popn_invert_complex: dgetrf -> singular

求助各位,麻烦给看看是怎么回事呢,谢谢。情况是这样的,计算Mg掺杂CuAlO2,结构优化成功了,后面计算dos的时候出错了,dos.castep里的内容是:

Pseudo atomic calculation performed for O 2s2 2p4
Converged in 25 iterations to a total energy of -429.5309 eV
Pseudo atomic calculation performed for Mg 2p6 3s2
Converged in 21 iterations to a total energy of -972.1949 eV
Pseudo atomic calculation performed for Al 3s2 3p1
Converged in 11 iterations to a total energy of -52.7384 eV
Pseudo atomic calculation performed for Cu 3d10 4s1
Converged in 51 iterations to a total energy of -1342.4825 eV

Error in popn_invert_complex: dgetrf -> singular
Current trace stack:
popn_invert_complex
